[Geschlossen] Continues loading translation loading issue & URL Structure Issue

Background of the issue:
I am trying to edit pages on my staging site (versteckter Link) after migrating from the Polylang plugin to WPML. I need to ensure the Chinese content from the live site (versteckter Link) is transferred to the staging site while maintaining the same URL structure. I am using the directory language structure and have attempted several approaches using hooks.

Symptoms:
I cannot edit my pages because the editor keeps loading without opening. The CN language is configured for Chinese, but the pages do not show the edit option. I have tried several approaches using hooks, but none of them worked.

Questions:
How can I resolve the issue of the editor continuously loading and not opening?
How can I ensure the Chinese content maintains the same URL structure on the staging site?
